The New Zealand ETA is an electronic travel authorisation that eligible travellers may need before travelling to New Zealand for a short visit or transit. It is generally linked electronically to the traveller's passport, so applicants should use the same passport when travelling. The NZeTA can be requested online or through the official mobile application. Before applying, check whether your nationality and travel purpose make you eligible. You may need to provide passport details, a photograph, travel information, and other required information. An approved NZeTA does not automatically guarantee entry, as border officers make the final decision on arrival. Travellers should also check whether they need to pay the International Visitor Conservation and Tourism Levy (IVL).
